SANDING-MACHINE.

SPECIFICATION forming part of Letters ZPatent No. 701,877, dated June10, 1902.

Application filed January 25, 1902. ,Serial No. 9l,1'79. (No model.)

- scription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

My invention relates to improvements in-' sanding-machines for vehicles,and especially to the class of devices particularly adapted for use oncars operated on railways.

The object of my inventionis to provide a sanding-machine which when inoperation will throw a quantity of sand at each side of the car at thesame time and immediately in front of the wheels.

Myinvention consists in providing new and improved means forsimultaneously operating separate sanding devices arranged on op positesides of a car.

My invention further consists in the features of construction andcombination of parts, as illustrated in the drawings and hereinafterdescribed in the specification, and pointed out in the claims.

In the accompanying drawings, Figure I is a horizontal section of thefront partof a car equipped with my sanding-machine, the section beingtaken just above the floor of the car and shows the floor partly brokenaway.

Fig. II is a section on lines 11 II, Fig. I. Fig.

III is a section on lines III III, Fig. II. IV is a section on lines IVIV, Fig. III.

Referring to drawings, a and a. represent the rails on which the cartravels.

b represents the floor of the car. p 1

c and 0 represent seats arranged along the respective sides of the car.

d and d, respectively, represent the forward wheels of the car.

On each sideof the car in the space underneath the respective seats arearranged hoppers e and f, respectively. The sides of each of therespective hoppers are inclined downwardly toward an opening in thebottom of the hopper, which corresponds to a similar Fig.

is mounted a screwconveyer g opening in thefloorof the car directlyunder each of the respective hoppers. A neck portion e is secured tothe'bottom of the hopper e, and it extends down'through the opening inthe floor of the car. To'theneck e is secured a casing g, which isarranged immediately in front of the wheel (1. The casing g is providedwith a spout g at its end adjacent to the wheel (Z. This spout g is ofsufficient length to extend down within a short distance of theraila'inbrder to secure the sand'being deposited directly on the rail infront of the wheel. The front end of the easing g is closed, and inthefront end and, in the rear end are formed bearings, in which The shaftof the screw conveyor is formed longer than the casing, so that itextends a short distance beyond the front end ofthe casing. On theprojecting end of the screw conveyor-shaft, close to the front end ofthe casing, iskeyed .a ratchet-wheel h. On the end of thisconveyer-shaft beyond the ratchet-wheel is rotatably mounted apawl-carrying head, preferably comprising an annular plate h of greatercircumference than the pawl-wheel. The said plate is provided with adepending arm portion 2'. On the face of the annular plate h adjacent tothe ratchet-wheel is mounted a pawl 11, arranged to engage the teeth ofthe ratchet-wheel h. Aspiring i is secured toplate h above 'the'pawl andis arranged to'hold the pawl'in engagement with,

the teeth of the'ratchet-wheel. The arms 2' of the pawl-carrying headson each side of the car are operatively connected by means of a rod-Zr,the ends of. which rod are hinged to the ends of the respective arms Zby pins i A shaft Z is arranged-above the connecting-rod la and at rightangles thereto and is supported by means of bracket Z, se-

cured to the floor of the car. On the rear end of the shaft Z is rigidlysecured a lever-farm Z0, which has its lower end hinged to theconnecting-rod It by means of a pin 70 To. the front end of the rod Z isrigidly secured a lever-arm Z. An operati ng-rod m extends down throughthe floor of the car and is connected with the lever-arm Z by means of apivot-pin Z This operating-rod mispreferably "formed ICO in two sectionssecured together by means of a pivot-pin m. A'spring n is provided forholding the lever-arm Z in its normal position parallel with the floorof the car, and, as shown in the drawings, one end of the spring issecured to the bottom of the car.

It will readily be seen that by depressing the operating-rod m motion iscommunicated to the lever-arm Z, which in turn rotates the shaft Z, anda corresponding motion is communicated to the respective pawl-carryingheads through the medium of the lever-arm 7c and the connecting-rod 70.As the pawlcarrying heads rotate the respective pawls t" engage theteeth of the respective ratchetwheels h, thereby actuating theratchetwheels, which in turn rotate the respective conveyers 9 therebyforcinga stream of sand through the respective spouts 9.

As shown in the drawings, my sandingmachine is arranged to be operatedby pressing the foot upon the operating-rod; butI do not desire to limitmyself to this mode of operation, as with a slight modification mydevice can be adapted to be operated by means of Steam, electricity, orany power used in operating the car.

What I claim is 1. The combination with a railway car or vehicle havingwheels arranged at opposite sides, respectively, of the car or vehicle,of hoppers arranged within the body of the car and at opposite sidesthereof, conveyer-cases located beneath said car and in opencommunication with the respective hoppers, discharge-spouts dependingfrom each of said cases, and arranged to discharge in advance of thesaid wheels of said cars, screw conveyors arranged within each of saidcases, and having their shafts extending beyond the end of the saidcasing, ratchet-wheels rigidly secured on each of the conveyor-shaftsoutside of said casing, a pawl-carrying head rotatably mounted on eachconveyer-shaft adjacent to the ratchet-wheels and having the pawl inengagement with the teeth of the said ratchet-wheel and means foroperatively connecting the respective pawl-carrying heads, substantiallyas described.

2. The combination with a railway car or vehicle having wheels arrangedon opposite sides respectively, of the car or vehicle, of hoppersarranged within the body of the said car, and at opposite sides thereof,conveyercases located beneath said car and in open communication withthe respective hoppers, discharge-spouts depending from each of saidcases and arranged to discharge in advance of the said wheels of thesaid car, screw conveyers located within the respective casings andhaving the ends of the conveyer-shafts extending beyond the ends of thesaid casings, a ratchet-wheel rigidly secured on each of theconveyer-shafts outside of said casing, a pawl-carrying head rotatablymounted on each of the said conveyer-shafts adjacent to the respectiveratchet-wheels, a pawl mounted upon each of the said heads and arrangedto engage the teeth of the respective ratchetwheels, a rod operativelyconnecting the said pawl-carrying heads, an operating-rod mountedvertically in an opening in the floor of said car and a bell-crank leverconnecting said operating-rod and the said connecting-rod, substantiallyas described.

3. The combination with a railway car or vehicle having wheels arrangedat opposite sides, respectively, of the car or vehicle, of hoppersarranged within the body of the said car and at opposite sides thereof,convoyercasings located beneath said cars and in open communication withthe respective hoppers, discharge-spouts depending from each of saidcasings and arranged to discharge in advance of the wheels of the saidcar, screw conveyers arranged within said casings having their endsprojecting through the ends thereof, ratchet-wheels keyed on each of theconveyorshafts outside of said casing, pawl-carrying heads rotatablymounted on each of the said eonveyer-shafts adjacent to the saidratchetwheels, a pawl mounted on the respective pawl-carrying heads andarranged to engage the teeth of the respective ratchet-wheels, a rodoperatively connecting the said pawl-carrying heads, a shaft mountedabove said connecting-rod and at right angles thereto, a lever-armforming an operative connection between said connecting-rod and saidshaft, an operating-rod mounted verticallyin an opening in the floor ofsaid car, a lever-arm forming an operative connection between the saidshaft and the said operating-arm, anda spring for holding thelast-mentioned lever-arm in its normal position, substantially asdescribed and for the purpose set forth.

In testimony whereof I sign the foregoing specification, in the presenceof two witnesses, this id day of January, 1902, at Toronto, Canada.
